Reproduce Happy Path

1. Run:

   docker-compose up --build --abort-on-container-exit --exit-code-from cypress
   

   The test should be executed successfully.

Reproduce Unhappy Path

1. Change CYPRESS_baseUrl to http://app:5000/ in docker-compose.yml file
2. Run:

   docker-compose up --build --abort-on-container-exit --exit-code-from cypress
   

   The test should hang (using Electron browser).
3. If you change the Cypress version to 4.12.1 in package.json and run:

   npm install
   docker-compose up --build --abort-on-container-exit --exit-code-from cypress
   

   The test is successful again. This is different behaviour from Cypress 5.1.0 where the test hangs.

Outcome

• When using Cypress 5.1.0 the test is hanging
• When using Cypress 4.12.1 the test is not hanging
